Hello,
I would like to cover the lower part of one of our walls with 13mm particleboard and the upper part with regular plasterboard.... Do you think the particleboard will move so much relative to the plasterboard that it will cause cracks in the joint compound at the seams?
The reason is that I want to hang a -long- radiator, and the ends stop halfway between two vertical studs, and I would like to have something stable to screw the brackets into.
I don't want to add additional studs because it's already insulated and has a vapor barrier. Additionally, there are some conduit pipes running horizontally through the framework that are in the way... do you think it will work, or is it better to bite the bullet and remove the insulation, vapor barrier, and conduits.. :-/

I honestly don't believe in your idea. Unfortunately, you will get movement between plaster and chipboard. I would invest in using double boards with chipboard + plaster. That's what I have at home everywhere, and with the right quality of chipboards (e.g., Byggelit boards), it is possible to mount kitchen cabinets without stiffeners.
An alternative is to use OSB (previously referred to as "flis," but that doesn't sound cool...) + plaster. Make sure the OSB boards are installed with a movement allowance of 3mm. Use the folding ruler as a spacer between the boards. The OSB boards have a width measurement of 1197mm for this reason.

Thanks for the response, good that you're honest 
Yes, that was probably what I suspected might happen.
A little issue is that there are 3 windows in the wall as well (hence the long element) and they protrude 13mm - just enough for a layer of plasterboard or equivalent. For double layers, I would have to fiddle with the window moldings, and I would prefer to avoid that.
The element will be 260cm long and the existing studs (45x145) are positioned so that the element will lack support for the last 90cm at both ends... it doesn't feel good to have 90cm unsupported at the ends...
Any more tips?

13mm particle boards do not exist; they are 10, 12, 16, 19, or 22mm thick. There are also thicker ones, but that's not what we were talking about...
As already written, your idea isn't great, but I suggest you put OSB or plywood behind the plasterboard and then install molding around your windows. They are adequately thick and cover nicely.
Then you can also hang paintings or cabinets on that wall without any problems.
